The tiny frog eggs have no shell. They are covered with clear jelly. The frog eggs stick together in big clumps. Inside each egg is the beginning of a frog. The black dot is a tadpole growing. The tadpoles change as they grow. Something wonderful begins to happen. Frog eggs Tadpoles 4 5
The new tadpoles hatch from their eggs. They look like little fish. The tadpoles have gills like fish to help them breathe under water. The tadpoles eat tiny water plants. Now hind legs grow. After a while the tadpole grows lungs. Lungs let the tadpole breathe air too. Something wonderful is happening. Hind legs Gills 6 7
Now the tadpole changes again. Front legs come out, one at a time. Its eyes grow larger. Its mouth grows wider. Now it looks like a frog with a tail. The tadpole s tail goes away. Then it crawls out of the water. The tadpole is a froglet. The froglet has shed its tadpole skin. Something wonderful has happened. Front legs Froglet 8 9
The tadpole has become a frog. It can live on land or in the water. The frog uses its long, sticky tongue to eat insects. One day the frog will lay eggs in the pond. Inside each egg a tadpole will change and grow. Something wonderful will happen all over again. Frog Sticky tongue 10 11
